The lactase supplement adds beneficial bacteria to a person's diet. These bacteria populate the stomach and prevent dairy digestion.

The Lactaid supplement provides vitamins and minerals that are missing from a person's diet. These types of nutritional supplements provide nutrients to lead to a healthier diet.

The Lactaid changes milk into a neutral water solution, which makes it a good source of fiber, vitamins, antioxidants, and minerals.

Consuming lactase, the enzyme specific for lactose digestion, helps the body break down lactose more quickly in the stomach and small intestines.

Temperature of 40^oC and a pH of 8

Temperature of 37^oC and a pH of 6

Temperature of 50^oC and a pH of 10

Temperature of 27^oC and a pH of 4

A substrate will be unable to attach to the enzyme.

The enzyme will be unable to produce more enzymes.

A substrate will be able to bond with the enzyme.

The enzyme will likely be attacked by immune cells.

The enzymes were very active and prevented the breakdown of hydrogen peroxide.

The enzyme was removed from its optimal environment, causing it to denature and lose its ability to function

The enzymes were in optimal conditions, causing the enzymes to break down their substrates.

The results in tubes 1 & 3 can best be attributed to experimental error.

The bacterial enzymes are denatured by the high heat causing the bacteria to die.

The bacteria slow down at these lower temperatures and are unable to grow.

The bacteria grow uncomfortable and leave the food for better environments.

The bacterial enzymes are denatured by the change in pH causing the bacteria to die.

Enzymes are destroyed when they are used

Enzymes briefly attach to the reactant during a reaction

Enzymes can be reused

Enzymes always have a specific shape

Starch molecules are too large to be separated.

Enzymes are specific to a substrate

Starch is composed of amino acids

Egg white acts as a coenzyme

bind to a substrate, transform itself into more of the substrate, and release higher amounts of the substrate as a product

bind to a substrate, transform itself and the substrate into products, and cause these products to dissolve

bind to a substrate, transform the substrate into products, and release the products.

bind to a substrate, transform itself into products, and release these products into the substrate
